C# 使用SSH.NET中的jumphost执行命令

我正在使用SSH.NET库在（Red Hat）服务器上执行一个命令，如下所示：

var response = string.Empty;
using (var client = new SshClient("<host>", "<username>", "<password>"))
{
   client.Connect();
   var cmd = client.CreateCommand("<some command>");
   response = cmd.Execute();
   client.Disconnect();
}

ssh <user>@<server>

Pseudo-terminal will not be allocated because stdin is not a terminal.
